a large cohort (145) of undergraduate students in a module assessed through two separate group projects. Students self-selected groups for the first project; for the second, groups were more 'balanced'. Results showed a slight improvement in group performance compared with that of previous cohorts, with a significant increase in first-class grades. No evidence was found linking group balance to performance; however, students recognized the value of their Belbin report when entering the job market. Other team role inventories Team Management Profile (TMP) A competitor to the Belbin system, developed independently in Australia by Charles Margerison and Dick McCann, is the Margerison–McCann Team Management Profile. This can be shown as a similar wheel with rather similar roles, whose titles however are different. The company states: "Independent British Psychological Society reviews (1995, 2000 and 2003) on the Team Management Profile are available" Star Roles Model The Star Roles Model is used by organisations to describe the positions managers and mentors adopt when guiding direct-reports and mentees. The concept builds on the Group Roles model developed by Benne & Sheats in 1948, taking a short-cut route to describing preferences when guiding others. Similarly, the Roles Model follows the Mintzberg 10 management positions – drawing in the most relevant elements when considering the mentoring relationship in detail. Myers–Briggs Type Indicator The Myers–Briggs Type Indicator is a theoretical model of a person's preferences and how people perceive the world around them and make decisions.
